Method and central control entity for controlling data plane flow of packet flow

Abstract

The invention relates to a central control entity (200) configured to control a data plane flow of data packet flows in a radio access network part of a mobile communication network. The central control entity (200) includes: an information detection unit (210) configured to detect and connect to a data plane application (41-44) of a forwarding unit (120-124; 131-134) attached to the radio access network part ), and is configured to detect information related to at least one data plane application (41‑44) to be applied to the data plane flow. In addition, the central control entity (200) includes: a control unit (230), configured to: determine the path of the data plane flow through the forwarding unit (120-124; 131-134) of the radio access network part, wherein, The control unit (230) is configured to: determine the path considering the at least one data plane application (41-44) to be applied to the data plane flow, the control unit (230) is also configured to: indicate that in the path The forwarding unit to which the at least one data plane application is attached passes the data plane flow through the at least one data plane application (41-44).

Description

technical field [0001] The invention relates to a central control entity configured to control a mobile communication network, a method for controlling a data plane flow by the central control entity, and a forwarding element of a radio access network part forwarding the data plane flow Data plane flow of packet flow in the radio access network part. Background technique [0002] Today's mobile backhaul (MBH) network / radio access network is usually structured in two parts, the High-RAN (Radio Access Network) part and the Low-RAN part, to provide connectivity and connectivity for mobile packet data from cell sites to the core network Business collection. available from figure 1 As seen in , the High-RAN part generally uses a ring topology with network nodes 20 to 24, while the Low-RAN part uses a tree structure with network nodes 31 to 34. The cell site is connected to the Low-RAN. Low-RAN generally uses a microwave link connected to the access branch of the High-RAN ring...

Problems solved by technology

However, while this simplifies the site itself, it introduces complexity to the router

Router platforms cannot accommodate processing-intensive functions, and router size has become an issue

Furthermore, scalability issues arise when data plane flows to be passed through data plane applications increase

[0009] Therefore, multiple data plane applications (such as image 3 shown) may be a short-term solution, but not scalable into the future, especially with the predicted increase in packet traffic

[0010] Increased demand for multiple data plane applications and increased mobile packet data traffic creates scalability and overhead issues for edge routers and data plane applications
